Objectives: Diabetes is a primarily self-manageable condition. Healthcare professionals usually offer education, treatment, and support, but patients themselves are responsible for the daily management of their condition. Increasing the effectiveness of self-management support may have a considerable impact on health care, especially for elderly people. The aim of this study was to describe diabetes self-care among elderly diabetics and to determine its associated factors. Methods: This report describes a cross-sectional study involving 143 elderly diabetes patients in the outpatient department of the Hospital Universiti Sains Malaysia (HUSM). Self-care activities assessed in this study included dietary control, physical activity, self-monitoring of blood glucose, medication adherence, and situational related adherence behaviour, all of which were obtained using the validated Malay Elderly Diabetes Self-Care Questionnaire (MEDSCaQ). Results: The mean (±SD) age of the subjects was 67.9 (±5.4) years old. A majority was Malay, with a mean HbA1c of 8.4 (±1.9). The mean diabetes self-care score was 26.5 (±8.0). Factors with a positive impact on diabetes self-care included being non-Malay (β = 5.275, p = 0.002), having family as care givers (β = 8.995, p = 0.004), having a higher level of family support (β = 0.159, p = 0.042), and possessing acceptable (β = 4.375, p = 0.001) or good knowledge of diabetes (β = 5.893, p = 0.004). The presence of neuropathy negatively impacted self-care, while diabetes nephropathy had a positive impact on self care (β = −4.053, p = 0.003). Conclusions: Elderly individuals with type 2 diabetes in HUSM have a moderate score of diabetes self-care practice based on the MEDSCaQ. Determinants for good diabetes self-care include race, social support, having care-takers during periods of illness, diabetes knowledge, and diabetic microvascular complications.
